Photographer Paola Nunez Solorio has been documenting the often poor infrastructure of schools in the Mexican states of Morelia, Oaxaca and Michoacan.

Under the education reforms, a census will establish the exact number of schools, teachers and pupils in the country. Teachers will be required to take tests before they can get jobs or be promoted.

President Pena Nieto says Mexico's future depends on the reforms, but some unions argue testing teachers who lack even the most basic teaching tools and infrastructure is unfair.

Many rural schools, such as this one in the Costa region of Oaxaca, could only be built because parents donated money towards the building project.

In some of the smaller and more remote schools, children of different ages are taught together.

During the winter, some pupils have to endure cold and rain, while in summer they suffer from dehydration because of the heat.

Many students commute from far away, usually on foot.

Some schools rely on funding from charitable organisations in Mexico and abroad.

Bilingual schools are common in rural communities in Oaxaca where a large percentage of the population does not speak Spanish or speaks it as a second language. Oaxaca currently has 16 officially recognised native languages besides Spanish.

Even the schools which are connected to the electricity grid suffer frequent blackouts, and children have no way to make up for lost lessons.

Fewer than half of the 15-year-olds complete elementary school. President Pena Nieto hopes his reforms will change this.
